To all @071 0m it may concern:

Be it known that I, Josnrrr B. ARMITAGE, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Ithode Island, have invented a new and useful Improvement in Vaulting Horse- Bucks, of which the following is a specification.

This invention relates to certain new and useful improvements in vaulting horse bucks and relates more particularly to the means for causing engagement of the casters with the floor to enable the apparatus to be moved from one place to another in the gymnasium.

The primary object of the invention is to provide means whereby the casters may be moved from a point at the top of the apparatus to engage'the floor without any movement of the top of the horse buck independent of the entire structure and to also enable the casters to be moved to engage the floor regardless of the position of the top of the horse buck, 2'. 6., whether said top is in high or low position. I

A further object of the invention is to provide means which is permanently and at all times in position ready for actuation to cause engagement of the casters with the floor.

A still further object of the invention is to provide caster actuating means which is coupled with the raising and lowering means of the horse buck top, so that the movement of the latter positively effects variation of movement of the caster actuating means so as to maintain the latter in position ready for operation throughout any and all positions or range of elevations which the top of the horse buck is capable of having.

In the drawings-Figure 1 is a fragmentary vertical sectional View of the top part of a horse buck embodying the present invention. Fig. 2 is a fragmentary vertical sectional view of the bottom part of the horse buck. Fig. 3 is a fragmentary detail view. Fig. 4 is a side elevation, partly in vertical section of the complete invention, and Fig. 5 is a detail view.

The base 1 has hollow ends, and also has a vertical column 2 thereon, which latter receives on its interior the hollow depending stem 3 of the top 4. A shoe 5 is pivoted at 6 to the base 1 and carries a caster 7, the shoe and caster when the apparatusis being used for exercising purpose being received within the base so as to allow the latter to directly engage with or seat on the floor as depicted in Fig. 2 of the drawings.

Rigidly secured to the base 1 and projecting upwardly therefrom is an interiorly threaded tubular post 8, into which extends and engages the lower threaded end of a rod 9. The rod 9 is connected to the top 41 and is rotatably mounted in a bearing 10 formed on the head 11 of the stem 3, the head 11 being rigidly connected to the top 4- in any suitable manner. A cap 12 is affixed to the upper end of rod 9 and seats on the upper end of the bearing 10. For the purpose of preventing upward movement of the rod 9, a thrust ball bearing 13 is interposed between the under face of head 11 and the upper end of a gear 14 which latter is rigidly secured to rod 9. Rods 9 are operated by any suitable means, common to horse bucks and upon rotation will raise or lower the top 4, as desired, through the rods 9 and the posts 8.

For the purpose of engaging the shoe 5 so as to lift the base 1 up from the floor, a pair of rods 15 are provided which rods have their lower ends connected to a coupling 16, to the lower end-of which latter a rod 15 is secured, the rod 15 hearing against set screw 17 which is carried by the shoe. The rods 15 are slidingly guided in apertures provided therefor in a head 18 formed on the upper end of the post 8. A cross head 19 connects the upper ends of the rods 15 and has a central threaded bore through which passes a threaded rod 20, the rod 20 having a gear 21 on its upper end portion which meshes with the gear 14 of the rod 9, the gear 141 being of such length that same will remain in mesh with the gear 21 throughout the sliding movements of rod 20 which carries gear 21 in its up and down movements. The stationary post 8 by virtue of its head 18 engaging the pair of rods 15 prevents rotating movement of the latter.

It will be understood that all of the mechanism above described is duplicated at each end of the apparatus.

A rotary disk or member 22 is carried by the top 4: of the horse buck and has the curved ends of a pair of levers 23 pivotally secured to diametrically opposed points thereon, the handle 24 being connected to member22 whereby to rotate same. A bell crank lever 25 is pivotally secured at '26 to the head 11 of stem 3 and has one arm pivoted to the adjacent lever 23 and its other arm bearing on the upper end of rod 20.

In operation, downward movement of handle 24 causes outward movement of the levers 23 and therewith outward movement of the vertical arms of the bell crank-s and downward movement of the horizontal arms of the bell cranks the, latter exerting downward pressure on the rods 20 and since the latter are connected to the rods 15 by the cross head 19, the rods 15 will be depressed to cause rods 15 to exert pressure on the set screws 17 of the shoes 5, thus effecting raising of the base 1 relative to the, floor, bringing the casters into operative position. In rotating the rod 9 so as to raise or lower the top of the horse buck, gear 14 by virtue of meshing with gear 21 will rotate the latter and thereby the rod 20, the latter causing corresponding up or down movement of cross head 19 and rods 15, thus at all times maintaining the rods, in engagement with the shoe, whereby when the bell cranks exert pressure on said rods 15 the base 1 will be raised up free of engagement with the floor.

It is particularly to be noted that the present invention enables the apparatus to be moved up from the floor from the top thereof. and it is further to be observed that the entire means for effecting lifting .up of the base from the floor is concealed from view.

. Having thus described my invention, I claim as new and desire to secure by Letters Patent j 1. In combination with a base and the top of a vaulting buck and an adjustable connection between same consisting of a rigid tubular threaded post on the base and a threaded rod therein depending from the top. a pivoted caster carrying shoe, carried by the base, a perforated head on said post, a pair of rods slidingly arranged in said perforations, a cross head connected to the upper ends of pair of rods and having a threaded aperture, a threaded rod in said aperture, a member carried by the top which slidably supports said last named rod, intermeshing gears between the first and last named rods, a bell crank lever pivoted to said member and having its horizontal arm engaged with the upper end of the last named rod, a lever pivoted to the vertical arm of the bell crank, and means to actuate the lever.

2. In combination with a base and the top of a vaulting buck and an adjustable connection between the two including a rotatable member, a caster movable relative to the base. means to engage the caster to thereby enable the base to be raised relative to the caster, means actuated by the rotatable memher to simultaneously operate the caster engaging means so as to maintain same in position ready for operation throughout the movements of said rotatable member, and means independent of the rotatable member to actuate the caster engaging means.
